TO ALL WHOM IT MAY CONCERN Be it known that I, S. B. MANN, ofIndianapolis, in the county of Marion, end State of indiana, haveinvented a new and useful Improvement in Field-Rollers; und I do herebydeclare the following to be a full, clear, end exact description of thesame, reference being had to the accompanying drawings, forming part ofythis Specification, and in which the drawing represents a. perspectivevien" of' my invention.

In this invention the roller is a. hollow cylinder, in which are placedheavy metallic balls for the purpose of increasing the Weight Withoutchanging the bulk of' the apparatus. The spring that supports the seatis also arranged in a. novel manner.

In order that others skilled in the art to which my invention nppertninsmay be enabled to make anli use the same, I will proceed to describe itin detail. y

In tite drawings, A A are ports of the frame. B is the draw-beam. C Care braces to strengthen the frame and steady the drow-beam. B is thedriver's foot-rest.) Eis the drivers seat, resting on springs e e,attached to the freine in front of tbe-roller, at e e', and in its rearat e e". F is the roller-shaft, bearing in the frame A and drew-beam B.G G are the rollers, and H H H are heavy metallic balls placed inside ofeach of the rollers, so as greatly to increase their weight withoutaffecting in any degree their bulk, and for the further purpose of'enabling the operator to graduate the weightwf the rollers by insertingor removing any number of the balls; The Vends of the cylindricalrollers may be closed entirely, or the spokes I I may be placed so neereach other as to confine the balls `Within the rollers. The springs e eare simple flat springs 'bent over the rollers in a. semicircular shape,and attached at their ends to the frame, thus forming guards to therollers and supports end springs tothe sect, and all of the simplest,cheapest, and most durable construction.

Hoving thus describecl my invention, what I claim es new, and desire tosecure by Letters Patent, is-

The combination and arrangement of the hollow cylindrical rollers G Gwith the metallic balls H H H, as

and for the purpose specified.
